AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
322 PM EDT FRI JUN 11 2010

.SYNOPSIS...
A WARM FRONT WILL CONTINUE TO MOVE NORTHEAST OF THE AREA OVERNIGHT
ALLOWING MUCH WARMER AND HUMID AIR INTO THE REGION. LOW
PRESSURE WILL MOVE EAST ACROSS THE LOWER GREAT LAKES REGION AND
FORCE A COLD FRONT ACROSS THE AREA ON SUNDAY.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
THE WARM FRONT IS MAKING SLOW PROGRESS ACROSS THE FORECAST AREA
THIS AFTERNOON WITH A FEW SCATTERED SHOWERS ASSOCIATED WITH THE
FRONT. WELL SOUTHWEST OF THE FORECAST AREA...THUNDERSTORMS
DEVELOPED AND THEY WERE MOVING SLOWLY NORTH TO NORTHEAST. THE AIR
MASS BEHIND THE WARM FRONT IS RATHER MOIST WITH DEW POINTS IN THE
LOWER TO MIDDLE 70S AT THIS TIME. THIS AIR MASS IS EXPECTED TO
ADVANCE NORTHEAST INTO THE REGION DURING THE NIGHT. I AM
ANTICIPATING THAT THE LOWS WILL OCCUR THIS EVENING AND WE WILL
START TO SEE RISING TEMPERATURES JUST BEFORE SUNRISE AS THE WARM
AIR MASS BECOMES ENTRENCHED.

SCATTERED SHOWERS AND THUNDERSTORMS CAN BE EXPECTED OVERNIGHT
TONIGHT IN THE TROPICAL AIR MASS AND IT APPEARS THAT THE RAINFALL
RATES WILL BE QUITE HIGH. PRECIPITABLE WATER VALUES WILL EXCEED 2
INCHES LATER TONIGHT AS THE WARM MOIST AIR ARRIVES. THIS MEANS
THAT SLOW MOVING THUNDERSTORMS WILL BECOME EFFICIENT RAIN
PRODUCERS AND VERY HEAVY RAIN CAN BE EXPECTED AT TIMES. I AM GOING
TO HOLD OFF ON A FLOOD WATCH BECAUSE ANY FLOODING THAT OCCURS WILL
BE EXTREMELY LOCALIZED TO THE SLOW MOVING STORMS.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH TUESDAY NIGHT/...
THE THREAT FOR SHOWERS AND THUNDERSTORMS WILL BE ONGOING TOMORROW
AS A LOW PRESSURE SYSTEM MOVES NORTH OF THE AREA AND FORCES A WEAK
TROUGH ACROSS THE REGION. THIS TROUGH AXIS MAY BE THE FOCUS FOR
THUNDERSTORMS. DUE TO THE INSTABILITY AND THE KICKER MOVING
THROUGH THE REGION...SOME OF THE THUNDERSTORMS COULD BECOME
SEVERE...ESPECIALLY IN THE AFTERNOON INTO THE EVENING HOURS.

WE MAY SEE SOME MORNING SUN AND THAT WILL HELP TO BOOST
TEMPERATURES UP FOR THE AFTERNOON. THIS WILL FURTHER HELP TO
DESTABILIZE THE ATMOSPHERE AND INCREASE THE THREAT FOR SEVERE
WEATHER IN THE AFTERNOON.

STRONG WARM AIR ADVECTION INTO THE REGION WILL CAUSE TEMPERATURES
TO CLIMB WELL INTO THE 80S...ESPECIALLY IN THE NORTH WHERE SOME
DOWN SLOPING CAN ASSIST IN BOOSTING TEMPERATURES BY 3 TO 4 DEGREES.

THE LOW PRESSURE SYSTEM WILL BECOME NEARLY STATIONARY OVER LAKE
ERIE SATURDAY NIGHT AND A COLD FRONT WILL APPROACH FROM THE
NORTHWEST. THE FRONT WILL MAKE SLOW PROGRESS MOVING SOUTHEAST AS A
WEAK WAVE OF LOW PRESSURE DEVELOPS ALONG THE FRONTAL BOUNDARY.

EUROPEAN MODEL HAS BEEN CONSISTENT IN BRINGING DRIER AIR INTO THE
REGION ON MONDAY AND WE SHOULD SEE THE THREAT FOR SHOWERS AND
THUNDERSTORMS START TO PULL OUT OF THE AREA IN THE MORNING. WILL
CONTINUE THE TREND FOR DRYING CONDITIONS BY AFTERNOON. WEAK HIGH
PRESSURE BUILDS IN FOR MONDAY AFTERNOON AND MONDAY NIGHT.

YET ANOTHER WARM FRONT WILL APPROACH FROM THE WEST ON TUESDAY.
FRONT WILL SEND A SURGE OF MOISTURE AND ANOTHER THREAT FOR SHOWERS
AND THUNDERSTORMS TUESDAY IN THE WEST.

TEMPERATURES SETTLING BACK DOWN AFTER COLD FRONT MOVES THROUGH THE
AREA SUNDAY INTO SUNDAY NIGHT.  NOT AS WARM FOR MONDAY AND TUESDAY.

&&

.LONG TERM /WEDNESDAY THROUGH THURSDAY/...
GFS AND ECMWF DIFFER ON WEAK FEATURES WED THROUGH FRI. BEST SHOT AT
DRY WEATHER APPEARS TO BE THU AS SURFACE RIDGE SEEMS TO BE MOST
DOMINATE THAT DAY. JUST CAN'T COMPLETELY IGNORE THE WEAK TROUGHING
AND FRONT PER THE ECMWF ON FRI AND GUIDANCE POPS AT SLIGHT CHANCE SO
SEE NO REASON TO FIGHT THIS. WILL CONTINUE WITH SLIGHT TO LOW CHANCE
POPS WED...GO DRY FOR THU AND BRING BACK A SLIGHT CHANCE FOR FRI
AFTERNOON.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
A WARM FRONT SLOWLY LIFTING INTO THE LAKE ERIE AREA TONIGHT WILL
HELP TO TRIGGER SHOWERS AND THUNDERSTORMS...ESPECIALLY DURING THE
MORE FAVORABLE LATE AFTERNOON AND EVENING HOURS. MUCH OF THE
CONVECTIVE ACTIVITY FROM THIS MORNING OVER THE WEST HAS DISSIPATED
AND WILL PROBABLY REMAIN RATHER QUITE FOR THE NEXT HOUR OR TWO. THEN
BY LATE AFTERNOON INTO EARLY EVENING NEW CONVECTION WILL SPREAD NE
TOWARD THE WESTERN TAF SITES. CONDITIONS IN THE TSRA CAN DROP TO IFR
IN SOME OF THE HEAVIER...WIND BLOWN RAIN. OUTSIDE OF THE
RAIN...MAINLY EXPECT VFR OR HIGH END MVFR TO CONTINUE TONIGHT AND
SATURDAY. THERE IS ALSO A SMALL CHANCE THAT A CLUSTER OF TSRA MOVING
ACROSS SOUTHERN CANADA COULD TURN SE AND BE NEAR ERI LATE TONIGHT.

.OUTLOOK...NON VFR LIKELY AT TIMES LATE SATURDAY INTO SUNDAY AND
POSSIBLE MON AND WED IN SHOWERS AND THUNDERSTORMS.

&&

.MARINE...
WARMER TEMPERATURES MOVING OVER THE LAKE TONIGHT INTO SATURDAY
SHOULD HELP TO KEEP WINDS 15 KNOTS OR LESS. A COLD FRONT MOVING
THROUGH ON SUNDAY COULD BRING WINDS UP ENOUGH TO APPROACH SMALL
CRAFT CONDITIONS BUT THE GENERAL CONSENSUS IS THAT WE WON'T QUITE
GET THERE.  WINDS AND WAVES TONIGHT INTO SUNDAY WILL BE LOCALLY
INFLUENCED BY OUTFLOW FROM NUMEROUS THUNDERSTORMS...SO EXPECT TO
FIND CHOPPY CONDITIONS AT TIMES.

PRIMARILY A NORTH FLOW SHOULD PREVAIL MONDAY. THE MODELS DIFFER MORE
AND MORE TUE INTO WED SO NOT CONFIDENT IN WIND DIRECTION BUT UNDER
EITHER SCENARIO EXPECT TO SEE WINDS GENERALLY STAY 15 KNOTS OR LESS.
